Modelling Drug ConcentrationA drug trial is studying the efficacy of a new drug for thalassemia, a genetic disorder in which a patient isunable to properly synthesize the hemoglobin molecule in the blood. In the trial, the rate at which thedrug is metabolized by the body is studied. The data from the trial is then used to construct a model forthe drug's metabolism. The concentration of a drug, f(t) in parts per million, in a patient's blood thours after the drug is administered is given by the functionf(t) = -t5 + 3t* – 6t3 – 2t? + 60tThe goal of this tutorial is to graph this function and analyze and interpret the graph within the problemcontext.Show the following steps on the blackboard or paper as your instructor directs:d) Use the procedure for sketching polynomial functions (p. 189) to sketch the graph for f(t). Showclearly all steps of this procedure.e) Identify the practical domain on your graph and state the practical domain in interval notation.f) Using your graph, estimate when the drug attains maximum concentration. Check your answer byusing graphing software (graphing calculator, wolframalpha phone app or website, desmos.com, etc).

Table 4.18 shows estimated effects for a fitted logistic regression model with squamous cell esophageal cancer (1 = yes, 0 = no) as the response variable Y. Smoking status (S) equals 1 for at least one pack per day and 0 other- wise, alcohol consumption (A) equals the average number of alcoholic drinks consumed per day, and race (R) equals 1 for blacks and 0 for whites. A. To describe the race-by-smoking interaction, construct the prediction equation when R = 1 and again when R = 0. Find the fitted YS conditional odds ratio for each case. Similarly, construct the prediction equation when S = 1 and again when S = 0. Find the fitted YR conditional odds ratio for each case. Note that, for each association, the coefficient of the cross-product term is the difference between the log odds ratios at the two fixed levels for the other variable. B. In Table 4.18, explain what the coefficients of R and S represent, for the coding as given above. What hypotheses do the P -values refer to for…
Active oxygen and free radicals are believed to be exacerbating factors in causing cell injury and aging in living tissue . Researchers are therefore interested in understanding the protective role of natural antioxidants. In the study of one such antioxidant (Hsian-tsao leaf gum), the antioxidation activity of the substance has been found to depend on concentration in the following way: dA(c)\dc=k[L−A(c)], A(0)=0.dA(c)dc=k[L−A(c)], A(0)=0. In this equation, the dependent variable AA is a quantitative measure of antioxidant activity at concentration cc. The constant LL represents a limiting or equilibrium value of this activity, and kk a positive rate constant. Let B(c)=A(c)−L and reformulate the given initial value problem in terms of this new dependent variable, B.dB(c)/dc= B(0)= Solve the new initial value problem for B(c)and then determine the quantity A(c).A(c)= Does the activity A(c) ever exceed the value L? ? yes no Determine the concentration at which 95% of the…

Consider an equation to explain salaries of CEOs in terms of annual firm sales, return on equity (roe in percentage form), and return on the firm’s stock (ros, in percentage form): log (salary) = β0+ β1 log(sales) + β2roe + β3ros – u. In terms of the model parameters, state the null hypothesis that, after controlling for sales and roe, ros has no effect on CEO salary.

A country is to establish a zone in the sea adjacent to its coast in which no fishing is to be allowed. This is to be done to protect a species of fish which, in the absence of fishing, would grow exponentially due to births which are proportional to the density of the fish. Outside the zone, which extends from the shore to a distance L out to sea, all the fish are harvested by deep-sea trawlers. The fish move about at random in the direction from the shore to the zone's boundary and so effectively diffuse in this direction. If L is too small, the effectively immediate destruction of the fish which wander out of the protection zone will cause a loss of fish that may exceed their ability to reproduce; this would lead to eventual extinction. 1. Formulate a model of the dynamics based on the conservation of fish, their breeding and their movement.
